Down the tunnel you hear an ominous hiss of steam, and the heavy chugging motions of gears and pistons. A light appears at the end of the tunnel... oh... oh crap, it's coming this way! RUN!

Flying steam trains, the cloudrail golem is designed with transportation in mind. Traveling a swift 240 ft. feat in a single move action, it can travel the skies on rails of water vapor or fire, steam howling against the rush of wind. Within, a fire and a water elemental are bound, their interaction driving the engine ever faster.

Cloudrail golems are usually used to pull Cloudrail Carts, taking advantage of it's massive pulling capacity to transport large amounts of goods. Rarely are they used in combat, though it's swift movement means they provide an excellent escape for retreating troops.

This golem has is a large blocky steam engine made of iron and wood. It's from is decorated with a face, typically a dragon, a skull, or some other visage fitting for the owner. A cloudrail golem cannot speak, but it does make noises in the form of metallic growls, toots, whistles of steam, and loud bellows of its horn. It runs on wheels, but most of the time is airborne. It weighs around 5000 pounds and can store 4 medium creatures inside its body comfortably.

Cloudrail golems rarely fight, but when pressed into battle they usually come in charging, using their overrun and trample to knock the enemy prone and enjoying the AoO when they try to stand. The Steam Burst is used against crowds, and effective on fire-vulnerable creatures, though the golem does not have the intelligence to pick out who is vulnerable from sight. Unless commanded to do otherwise, the cloudrail golem will do whatever is best in the interest of self preservation.

Steam Burst (Su): Every 1d4 rounds a cloudrail golem may employ it's steam burst breath weapon, a 40 ft. cone of searing hot water vapor. It deals 8d6 fire damage, Reflex DC 18. The save DC is Con based. Due to it's watery nature, fire resistance is ignored when dealing damage, and fire immunity instead deals half damage to the creature, as if it were a Searing (Sandstorm) metamagic spell.

The Steam Burst deals 1d6 damage every 2 HD for advanced golems. For example, a 30 HD golem has a 15d6 Steam Burst.

Trample (Ex): As a full-round action, the cloudrail golem can move up to twice its speed and literally run over any opponents at least one size category smaller than itself. The cloudrail golem merely has to move over the opponents in its path; any creature whose space is completely covered by the cloudrail golem is subject to the trample attack. If a target’s space is larger than 5 feet, it is only considered trampled if the cloudrail golem moves over all the squares it occupies. If the cloudrail golem moves over only some of a target’s space, the target can make an attack of opportunity against the cloudrail golem at a –4 penalty.

Trampled opponents can attempt attacks of opportunity, but these take a –4 penalty. If they do not make attacks of opportunity, trampled opponents can attempt Reflex saves DC 29 to take half damage. The save DC is Str based. A cloudrail golem can only deal trampling damage to each target once per round, no matter how many times its movement takes it over a target creature.

Flight (Su): The cloudrail golem may fly at will at its land speed with average maneuverability. Like the Fly spell, if its flight is dispelled it drifts down for 1d6 rounds at 60 ft. a round before dropping.

Powerful Thrust (Ex): Due to it's build, a cloudrail golem is treated as a huge creature for determining encumberance. Also, since it lacks arms, all weight is considered pushed or pulled. As such, with it's strength of 33 it can pull as a light load, 16,000 lbs., as a medium load 16,001-24,000 lbs., and as a heavy load 24,001-48,000 lbs. This equals 32 empty cloudrail carts at full speed and up to 96 cloudrail carts at a reduced speed of 180 ft a round.

Smooth Rails (Ex): Powerful and unstoppable, the cloudrail golem can ride over sandy, muddy, or even swampy ground without difficulty or decrease in speed.

Water Rails (Su): The cloudrail golem is under the effects of Water Walk constantly.

Typically a cloudrail golem is used to pull massive amounts of supplies. As such, additional carts may be added to the golem. Each cart is a Large sized object which costs 5000g and has no notable stats of it's own. However, when connected to a cloudrail golem it gains the DR 10/adamantine, flight, and half the hp of the cloudrail golem. If a cart is disconnected, the separated carts treat as if the flight had been dispelled, and drift for 1d6 rounds at 60 ft. a round before dropping.

A cart can be targeted as its own creature, and should be considered a large sized creature which happens to be following and taking up space behind the actual golem. It holds up to 4 medium creatures comfortably and each weighs 500 lbs. unloaded.
